Application led lune 1,1901.

To all whom, t may concern.-

Be it known that I, CoRYDoN I. BUSH, a citizen of the United States of America, residing at `Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Syringes; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others to make and use the same, reference being had to the accompanying drawings, forming a part ofthis specification. I

The object of my invention is, first, a syringe for vaginal uses which will admit of the distention of the parts without injury thereto and which also may be employed in wounds of the body, whereby medicated solutions may be readily applied and the allaying and healing of infiammation expedited; second, to eftect the enlargement of the"` syringe in a greater or lesser degree in an outward direction of the stem; third, to prevent torsion in the outward extension of the springs of thesyringe; furth,"to retain ."the medi! cated solutions applied I by the syringe in vaginal applications; fth,to irrigate or medicate the parts of the body entered by the syringe by the backiiow of the solutions, and, sixth, to enable the outwardlyextensible springs to be readily detached from the stem of the syringe.

The invention consists in the novel construction and combination of parts, such as will be first fully described and then specifically pointed out in the claims.

In the drawings, Figure l is a side view of the syringe, showing the shield or dam and the springs on the syringe`stemdistended. Fig. 2 is.a view ofthe syringe with the dam removed and showing the outwardly-extensible springs in a closed position. Fig. 3 is a vertical sectional view of the invention as shown in Fig. l. Fig. 4 is a view of the outer end of the syringe-nozzle with the cap removed. Fig. 5 is an end view in detail of the perforate adjusting-collar for the outwardly-extensible springs of the syringe-stem. Fig. 6 is a view in detail of the forward end of the collar with which the inner ends of the springs of the syringe-stem are connected. Fig. 7

is a detail view in perspective of the collar` keyed on the threaded end of the stem of the Serial No. 62,6 79. (No model.)

Fig. 10 is a detail secf spending parts in all the figures of the drawings. l

Referring to the drawings, A represents a longitudinal hollow stem or tube for conducting fluids, in which is a longitudinal opening ct", extending through the end a and to within a short distance of the end d. rI he outer surface of the stem A is cylindrical in form and of corresponding thickness from its inner end a to a point intermediate its inner and outer ends, from whichpoint the stern gradually decreases in thickness,` and at the outer end a said stem is enlarged to nearly the circumference of its inner end.

. In theouter surface of stem A is a spiral groove a2, which extends from a point near the inner end of said stem part way toward the outer end of said stem.

Upon stem A is a longitudinal movable Wire-clamping collar B for adjusting the position of thewire springs of the syringe. From the forward end of collar B the annular surface b is reduced in size about two-thirds of the distance toward the outer end,the remaining rear end of the collar extending outwardly a short distance to form van annular shoulder b', which also presents a surface to be grasped by the fingers in operating the collar. The annular surface b of the collar is slightly inclined inwardly from the shoulder b for attachment of the dam, hereinafter described. Extending longitudinally through the collarfB are perforations Z22, which are spaced atlequal distances apart concentrically with tube A and correspond in numbers to the wire springs employe (l represents the slidable collar with which the inner ends of the wire springs ofthe syringe-stem i are connected and which is arranged upon the stem A in rear of the collar C. Upon the rear end of collar B is an exter- `nally-screw-threaded neck c, which is smaller in size than said collar. Extending longitu- IOO ployed being such as to afford convenient attachrnentto the stem A. The wire springs d in length are somewhat shorter than the length of stein A. The outer ends of the wire springs d are extended through the perforations c of collar C from the direction of the rear end of said collar and thence through the perforations b2 in collar B in the direction of the forward end of stem A. Extending from the forward end 0 of the tube or stem A, which for a short distance rearwardly is closed, is a screw 03. Concentric with said screw and within the end d of the stein is a depression 04, and extending outwardly from said depression to the outer side of the stem are radial depressions 05, which are increased in depth to that of the depression 04. In the depression 04 is a ring a, The outer ends of the wire springs d are extended within the depressions d5 in the end a' ofstein A and bent over the ring 06 to form ahook d', by means of which the outer ends of the wire springs are pivotally and also removably connected with the ring. Upon the end 0' of the stem A is an internally-screw-threaded cap 0,7, which is [pitted to the screw 0,3, and thereby prevents the accidental displacement of the wires d.

Y The outer surface of the cap 0.7 describes an outwardly-curved plane from the sides of the end a of the stern A. The inner ends of the wire springs d are bent at right angles in an outward direction from stein A to form stops d2 and said bent portions inserted in the depressions 02 in the rear end of collar C.

E represents a binding-collar, which is arranged on stem A in the rear of collar C and which binds the bent ends d2 of the wire springs d in the recesses c2 of said collar. In the forward end of collar E is an internal screw thread e, which receives the screwthreaded` neck c on collar C. Upon the rear end of collar E is a rearwardly-extended annular flange e', which extends half-way the distance around said end and is then bent inwardly a short distance to form the groove e2. The binding-collarE is turned upon the neck o of collar C and is slidable on the stern A in the following manner: In the threaded end of stem A is a longitudinal groove a8. In the rear end of the collar F., near one end of the annular flange e', is a depression e3, in which is inserted snugly a small stop or key e4, slightly less in width than the longitudinal groove 0S, the inner end of which stop is bent at right angles and extended within the groove 08.

F represents the operating-nut, which is larger in size than the collar E and arranged on the threaded end 02 of the stem in rear of said collar and which is provided with internal threads which engage with the threads d2 of the stein A. On the forward end of the nut F is a neck f', upon which neck is an annular outwardly-extended flange f2, which extends within the groove e2 of the collar E. The outer surface of the nut F is milled so as to be readily turned by the hand. In the arrangement of the collar E and nut F upon the stem A the flanged end of the nut is first placed within the groove e and both collar and nut are placed simultaneously on the stem and the collarF. turned on the shoulder o of the collar C, after which the key-e4isinserted in the depression e2 of the collar E, thus preventing the rotation of the said collar. Upon the extreme rear end of the stem A is an annular projection as, over which may be placed the end of the rubber hose connected with a bulb of a syringe. In the side of the tube or stem A near its foremost end are the outwardly-inclined orifices 010, which lead from the longitudinal passage 0.0. In the side of the tube or nozzle A, at a point about half-way between the outer and inner ends of the tube, are rearwardly-inclined orifices 012, which lead from the passage 00.

Gr represents the dam, which is made from a plate of hard rubber and elliptical in form. The central portion of the dam is concave, and in saidv portion is an opening which is of the proper size to fit the inclined annular surface b of the collar B and abut against the shoulder b', the convex side of the dam being directed toward the forward end of the stem A.

In operation, the parts being in the position as in Fig. 2, the collar B is seized by the iingers of the left hand and the nut F grasped by the fingers of the right hand and rotation imparted to the nut, which moves forward on the stem A, forcing the collars C and E forward toward the forward end of. said stein. This action causes the wire springs d d of the syringe-stein to extend in curved lines out-l wardly from the stem A. In order to increase the lines of curvature at the forward end of the stem A, the collar B is pushed forward by the fingers as far as necessary. The forward ends of the wire springs being pivoted, the wiresin rear of the collar are brought into a parallel position with the stem and an enlargement of the device effected in a greater or less degree as the collar is pushed forward. In vaginal treatment the syringe-stem is inserted in the position as seen in Fig. 2 and then expanded. The forward movement of the collar B, with the dam G, carries said dam to the point of entrance, and during the application of medicated solutions through the stem or nozzle A the darn prevents the escape of the solutions, which pass outwardly through the orifices al@ and also discharged in returning through the orifices 0.12.

For the treatment of wounds of the body Ioo IIO

the invention enables a more uniform distention of the wound and a more effectual treatment of the ruptured parts and without the danger of `incision in the application to the natural passages of the body when otherwise applied.

The dam G when pushed in position in the collar B is given a close connection and without leakage.

`Vith the removal of key e4t from the collar E and cap a7 the outwardly-extensible springs are readily detached from the stern A for cleansing and repair, thus aifording an in` strument of great utility and which may be connected with any source of Huid-supply for irrigation or the application of medicaments in surgical operations. The springs d may be made from steel silver-plated or from such other material as may be preferred.

VSuch modifications may be employed as are within the scope of the invention.
